Tankless Water Heater Problems We Solve

From intermittent hot water issues to complete system failures, our experienced technicians expertly diagnose and repair all tankless water heater problems. Don’t suffer through cold showers—contact Streamline at 919-263-5221 for fast, reliable tankless water heater repair service throughout Raleigh and surrounding communities.

Is your tankless water heater producing lukewarm water or constantly fluctuating temperatures? These issues often stem from scale buildup, sensor problems, or flow rate issues common in Raleigh‘s water conditions. Our technicians perform comprehensive diagnostics to identify the exact cause and implement lasting repairs that restore consistent hot water to your home.

Mysterious error codes or frequent system shutdowns can be frustrating and disruptive to your daily routine. Our specialized technicians are factory-trained to interpret diagnostic codes from all major tankless brands, quickly addressing underlying electrical, gas flow, or ventilation issues before they lead to complete system failure.

If your tankless water heater isn’t delivering the volume of hot water it once did, mineral scale buildup or component wear may be affecting performance. We’ll thoroughly clean your system’s heat exchanger, inspect all components, and optimize settings to restore maximum efficiency, helping you enjoy abundant hot water while controlling energy costs.
